Question

The escape velocity of a body depends upon its mass as

• A. $m^0$
• B. $m^1$
• C. $m^2$
• D. $m^3$

Answer 1

Answer: (A)

$m^0$

Answer 2

Escape speed of a body from Earth's surface is given by: $v _{\min }=\sqrt{2 gR }$ As we can see from the above equation, there is no 'mass' term. Implies it can be written as $m ^{0}$. So, the escape speed of a body is independent of its mass.
